The ACELP®.net family of codecs includes a dual-rate codec (8.5/6.5 kbps), a fixed-rate codec (5.0 kbps) and a wideband codec (16 kbps). The dual-rate version of ACELP®.net has the ability to switch bit rates on the fly to effectively handle network inconsistencies.
ACELP®.net provides toll-quality compression at
8.5 kbps and near-toll quality at lower rates. ACELP®.net wideband provides better intelligibility and richer sound than toll quality.
ACELP®.net is the preferred low bit rate speech codec in RealAudio® and is widely deployed in both Windows Media Player® and Audible® ready equipment.

This technology can be rapidly harnessed for closed-system applications such as broadcast over the Internet (multicasting), multimedia email and multimedia conferencing.
